Follow these checks in Audio Fix →When this guide applies
Exact iFi iDSD Diablo 2. Conventional less-sensitive front headphones work but remain too quiet in confirmed Normal mode. Rear4.4 mm line socket is unused and no hearing-protection cap is being bypassed.
Connection scope: USB audio · Optical digital audio · Bluetooth · Analog line / headphone audio. Symptom: Playback is too quiet or uneven.
This is a documented check, not a diagnosis of your equipment. The model name does not confirm the selected input, mode, software or connected partner.
If your exact model or a required setting is unknown, use the “I don’t know” branch below. Do not apply a similarly named model’s instructions.
Checks and possible outcomes

Look for: Confirm this exact setup and observation before continuing.
- If Yes, I confirm → Accept increased headphone power/gain?
- If No / my setup differs → Continue with source and model support

Accept increased headphone power/gain?
Turbo can substantially increase headphone loudness and battery demand. Continue only with rear line socket unused and agreement to lower volume first and compare cautiously. Do not use xMEMS or Nitro here.
Look for: Explicit informed acceptance is required before the next action.
- If I accept these effects → Pause and lower the dial
- If No / leave this unchanged → Continue with source and model support
